Google Groups Usenet
Google's archive of Usenet newsgroups, built on the DejaNews collection, with discussions reaching back to 1981. It has been frozen and read-only since 2024, and there is no API — you search and read through the Google Groups web interface we link to. Still one of the deepest places to find decades-old newsgroup threads and historical online discussion.
